Description
Technical field
The present invention relates to the recovery method of waste lithium cell, particularly the lithium cell recovery method of environment-friendly type.
Background technology
Lithium-ion secondary cell has the performance of many excellences, is extensive use of in portable, mobile plant and instrument such as mobile phone, notebook computer.According to statistics, global lithium ion battery turnout in 2005 is near 1,500,000,000; Estimate that 2010 annual production will be above 2,000,000,000, but along with the scrapping of these electrical equipment, a large amount of old and useless batterys are discarded and pile up, and considerable part is directly sneaked in the rubbish, and this pollutes environment, also is simultaneously a kind of waste to resource.Analytical results shows: every battery on average contains cobalt～15%, contains lithium～1.5%, and cupric～18% contains aluminium～5%, how to handle these batteries and reclaim wherein that valuable metal has become social hotspots.
Existing recovery technology about cobalt in waste lithium ion batteries mainly adopts molten, the method for extraction of acid at present, promptly adopts HCl, H
2SO
4, HNO
3Deng dissolving lithium cell positive material cobalt acid lithium, leach liquor is reached the purpose that the cobalt product is purified by extraction, back extraction, the most frequently used cobalt extraction agent is P507.Pan Ze waits the people by force, and (rare metal, 2002,26 (1): p39) proposing the recovery technology that lithium-ion secondary cell is produced the leftover bits cobalt, with dissolving with hydrochloric acid cobalt acid lithium, is precipitation agent with the ammonium oxalate again, directly precipitates cobalt oxalate, and direct yield is 91.5%.(University Of Tianjin's journal, 2006,36 (supplementary issues) p341) adopt sulfuric acid/hydrogen peroxide solution to leach to Yang Haibos etc., and the leaching yield of cobalt and lithium is big by 99.6%, but the precipitation that cobalt and lithium further are not discussed to reclaim.(applied chemistry, 2006,23 (10): p1182) adopt sulfuric acid/Sulfothiorine dissolving lithium battery powder such as Guo Liping, regulate pH and make precipitate and separate such as aluminium, iron, regulator solution pH9.5～10 make cobalt generate cobaltous hydroxide precipitation, filtered and recycled cobalt (rate of recovery is 97.8%).Wu Fang (the non-ferrous metal journal, 2004,14 (4), p697) adopt sulfuric acid/hydrogen peroxide to leach, the P204 extracting and purifying transfers to 5～6 with alkali with pH value of solution then, with P507 extracting and separating cobalt, use the back extraction of 2mol/L sulfuric acid then, extracting phase adds sodium carbonate solution and reclaims lithium then through concentrating.
Yet, in above-mentioned recovery technology, in order to improve cobalt acid lithium leaching yield, often adopt 1: 8～10 high liquid-solid ratio, sulfuric acid need be excessive greatly during leaching, and the P507 extraction agent requires pH of leaching solution will be higher than 3 usually, therefore before the extraction, often in leach liquor, add a large amount of alkali, in coming and the excess acid in the leach liquor, regulate about pH value to 3.Like this, raffinate can't recycle owing to contain a large amount of sodium sulfate, so produces a large amount of waste water in the technology, causes second environmental pollution.Wastewater treatment capacity is big, and in the alkali and consume a large amount of caustic soda, cost is higher.
Summary of the invention
The objective of the invention is to solve existing waste lithium cell cobalt and reclaim the problem that produces a large amount of waste water in the technology, the lithium cell cobalt that proposes a kind of environmental protection and saving type reclaims acid leaching-extraction process.
Concrete technical scheme of the present invention is: waste and old lithium electricity splits and obtains cobalt acid lithium and powdered carbon material and carry out counter current acid leaching with the sulfuric acid/hydrogen peroxide mixed solution of 1: 1～5 solid-to-liquid ratios under 25～90 ℃, consisting of of sulfuric acid/hydrogen peroxide mixed solution: sulfuric acid volumetric concentration 11～25%, hydrogen peroxide volumetric concentration 10～25%, one section leached mud send two sections leachings, in the slag that final stage leaches enrichment a large amount of charcoals, return acidleach workshop section again after sending roasting to take off charcoal; Adverse current leaches 2～4 sections, and making leach liquor pH is 2～6, and leach liquor send extraction process, and extraction agent consists of: P507:15～40%, and TBP 10～30%, sulfonated kerosene 30～60%; After the extraction, organic phase send the oxalic acid back extraction to sink cobalt, washing, drying; Wash water when raffinate is added sulfuric acid/hydrogen peroxide and filtration makes the sulfuric acid volumetric concentration reach 11～25%, and hydrogen peroxide volumetric concentration 10～25% is returned acidleach workshop section; Raffinate recycles 5～15 times; After lithium is enriched to concentration and reaches 2～10g/L in the raffinate to be recycled, with yellow soda ash lithium is precipitated as Quilonum Retard and separates.After waste water behind the sinker is sloughed part carbonate and sulfate ion through liming, qualified discharge.
With respect to prior art, the present invention consumes the vitriolic principle when utilizing the dissolving of cobalt acid lithium, making final pH of leaching solution by the multistage counter current leaching is 2～6, the pH value of final leach liquor extracts desired pH value harmony mutually with P507, therefore leach liquor does not need to add the alkali neutralization before extraction, just can contains sodium sulfate in the raffinate after the extraction, raffinate can enter recycle once more, after soon raffinate will be added sulfuric acid/hydrogen peroxide mixed solution, return leaching section again, so can be recycled 5～15 times, the waste water behind the only last sinker just discharges through after sloughing part carbonate and sulfate ion, and the waste water of discharging this moment also can reach emission standard.The present invention leaches by utilizing multistage counter current, make the pH value of leach liquor just in time reach the requirement of P507 extraction, can reduce alkaline consumption on the one hand, can also make the raffinate recycle once more after the extraction on the other hand, save the water in the technological process, and reduce 5～15 times of wastewater discharges.Although with respect to existing technology, the present invention is owing to adopt multistage to leach and the recycle of acid and water, and running cost can increase relatively, and the part that increases can be compensated from the minimizing of the alkaline consumption saved and discharge of wastewater fully, and totally cost still can reduce.
